Well tell you what guys...I will take a 351 clevo..blueprinted,balanced and maybe a stroker kit..with a holley 1150 cfm dbl pumper and I reckon I'd get close to 350/400 hp at the diff.

I don't like efi.

in the good old days when you had a bit of a stack or got into a bit of a scrape with a local down the pub you knew a clevo powered ambo would come to your aid.

nowdays youll get some european or asian rubbish (if it ever turns up that is) making its way to help well below the speed limit because it doesnt have the grunt of a clevo to overtake the camry in the way.

i say no thanks. i can drive my self to hospital quicker in the xa 351

Ok lets compare the Cleveland powered Cobra to the BOSS powered Cobra, 151kw vs 302kw or double the output from .4 litre increase in displacement.

ratter · 26-10-2007, 09:51 PM

A motor doesn't care if it's carburetted or injected, as long as it gets enough air and enough fuel to do what is intended.

A perfectly set up carb and perfect efi should result in the same top end power providing same inlet manifold styles are used, but the efi will normaly deliver more power throughout the rev range and better drivabilty and emissions

The peak reached by the SOHC 250 crossflow found in the ED reached 172 kilowatts in the AU XR6.

The DOHC six found in the BA/BF has hit a peak of 190kw naturally aspirated and 270kw turbocharged.

Even though it's the oldest I am under the impression that the best engine out of the 250 crossflow, BOSS and Cleveland is in fact the Cleveland 351..why???

The Cleveland is a oversquare design which encourages high rpm. I think engine builders have seen upwards of 400kw naturally aspirated in the Cleveland 351.

I'm sure the Cleveland guys have much better knowledge but the Cleveland 351 is in fact a new engine in relative terms. The BOSS 302 Mustang was used as a development fuel for the design of the excellent heads on the Cleveland and it was until the end of the muscle car era that the Cleveland was put into production which is a shame because the Cleveland had the potential to dominate the muscle car scene (which it did in Australia).

While not as powerful as the FE big blocks the big blocks were too heavy and inefficient for circuit racing and the Windsor small block was an outdated and restricted design by the late 60's.

For circuit racing the Cleveland was THE BEST engineavailable (though I think they had oiling problems).

Though many would dispute it there hasn't been a V8 to match the Cleveland since. The Windsor had shocking head flow and the Modular V8 is an overweight monstrosity with a design limiting it's ability to rev and be bored and stroked.

GM and Dodge took the path of in fact modernising their pushrod V8's from the 70's such a shame that we didn't get a modern Cleveland.

Don't be fooled by it's age remember man landed on the moon when the Clevo was released and that fest hasn't been matched since.

Hang on, werent the phase 3's a modded 351? So your comparing a modded 351 to a stock Boss?

MO · 26-10-2007, 09:57 PM

Give me the grunt, the sheer bloody mindeness and lack of ultra smooth response everytime.

If you've got a grunt 351 you drive the beast...not steer it like todays stuff.

Well seeing as this is a thread containing carbies, lets hope he has no Annular Discharge. BWAHAHAHAHAH

Why is there always a toilet humour reference in almost every thread on this forum???

Nostalgia · 26-10-2007, 10:32 PM

Not too sure. But you might want to refer to my post regarding Annular Discharge.

Now that my friend is plainly wrong. I have worked with carbs and fuel injection and can TELL you right now from experience with bosch fuel systems that efi atomises fuel droplets more efficiently

I don't like efi.

And i can take my 347 windsor fully balanced blueprinted and get 321 rw/hp. Give me a better eec management exhaust and 350 is on the cards

XCSEDAN · 26-10-2007, 11:04 PM

Carby V EFI
carby wins hands down, more tuneable, more economical, more powerful, and amazingly more reliable.
Barry Grant or someone did a MASSIVE Q&A about this, i remember reading it on the net a few months ago (don't know how old it was then), ill do my best to find it now

Nostalgia · 26-10-2007, 11:17 PM

To answer this thread correctly i would have to say the 428 is more powerful than the 351. The 460 is full of torque, but 428 is more user friendly. Please correct me if i wrong.

phase 3s came out of the factory like that mate, no aftermarket add ons ;)
so its the same, just like a boss 302/290 is an upgrade from a 260.
same same
in australia, everything same,
elephant lion same

The original question was..... "What ford engines are more powerful than a 351???", so I'm gunna say 427 SOHC !
There are NO Ford factory engines which are more powerful than this!

try these numbers out.
4.9 l 159 kw at 4600 revs , 364 nm at 3000 revs.
5.8 l 162 kw at 4500 revs , 429 nm at 2700 revs.
yes the cobra did come out with 2v 5.8's. surprise, surprise, and yes they were very inefficient because of ADR's in 1978 not because the engine was not capable of producing the numbers. if 40 years of development had gone into the clevo the boss engine would only be found in yank f trucks.
sorry but i don't see the relevance of this statement in the carby v's efi discussion.

Yes there are. Just none that went into production.

gtfpv · 27-10-2007, 01:07 AM

off topic but so is this whole thread . 351 GTHO PH 3 = 7 MILES TO THE GALLON
Which is 11.3km to 4.5 litres which is 2.5 km/ litre . which is 40 litres / 100km
boss 302 = 15.5 litres/ 100km

carboretors produce way more power . and air to fuel ratio for max power, with crap volumetric efficiancy / per cyl.

for an efi engine to do the same imagine the injectors and fuel pump needed.
of course the bottom end doesnt know the differance , but the efi would be more powerfull. one would think.

which means a BOSS 5.4 . with a holley 750 and throttle cable would shitee all over a 351. and an all out fuel injection setup to match the 750 holley would be better again

this is just my theory . i'd be interested to hear what a performance race engine builder thinks about my theory. this is assuming stock blocks and factory heads . for all engines mentioned here . the 351 having a holley 750.

Then what's the point...

steamin63 · 27-10-2007, 01:31 AM

just out of curiosity who has the most powerful n/a, pump fuel clevo/boss/windsor on the forum. no estimates or b.s. , real dyno numbers.

GK · 27-10-2007, 02:30 AM

One of the best experiences I ever had was in a mate's brother's XC Fairmont GXL with the 351.

We were on a quiet country road. He stopped the car. He revved it up, put it in drive and booted it. The throw back into the seat was awesome, the roar of that 5.8 was something else. First time I was in a car doing 200kmph.

Awesome. Aaaaaahhhhhh memories!
